Sawing of Solid Woods and Wood Based Materials with a Fret Saw Blade

摘要

In the sawing processes of solid woods and wood based materials with a fret saw blade, in order to make clear the sawing characteristics which are related to sawing-force components, saw-blade wear, machinability of the materials, sawing efficiency and so forth, a more fundamental research under the actual sawing conditions should be carried out. For that purpose, it is important and necessary to make clear the sawing-force components and the sawing phenomena. But few studies have dealt with the exact measurements of them, and so, the main objective of this study is to obtain quantitative information on them. In this study. the basic sawing tests of solid woods and wood based materials were performed, using an experimental apparatus designed for sawing with a fret saw blade. The main (Fp) and thrust (Fq) components of the sawing force were measured, And in addition to measurement of these components, the several sawing phenomena were observed and measured.Based on these results the sawing characteristics were discussed.
